Gear driven brush and belt vacuum

ABSTRACT

This is a vacuum cleaner that includes the installation of the presented vacuum cleaner. This unit would now include a gear driven brush, which connects, to the motor via a gear driven tension belt. Two roller bearings are provided to prevent damage and the overheating of the cleaner. The primary purpose of the gears on the brush and belt is to accommodate the smooth rotation of the belt and also the ability of the brush to rotate as fast or at the same pace as the motor, while at the same time maintaining alignment.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to vacuum cleaners and in particular, to a gear driven brush and motor via a drive belt.

2. Description of the Related Art

The present invention is an improvement to the typical hand held cleaner which has a floor engaged brush. A rotating brush is commonly enclosed in the base of the vacuum. A motor and a fan propel this brush, which is the essential operating device of a vacuum cleaner.

Typically a motor with a drive shaft and a cog pulley serves as a catalyst for the rotation of the brush via a belt. This belt driven system can often malfunction resulting in loss of tension in the belt thus the inability to effectively suction debris. With the inability of the brush to rotate adequately the cleaning ability of the vacuum is compromised and impaired. The user is left with a noisy and ineffective vacuum cleaner, which can be very unpleasant.

A major factor affecting the tension belt, which is common in today's vacuum is the inability of the motor to keep proper tension on the belt over time. As with any other product with repeated use comes wear and tear however, with the above mentioned components excluded from the initial assemble of a vacuum cleaner comes a shorter life span or product durability.

Notably so, the major contributing factor affecting the tension of the belt is the placement and mounting of the belt to the motor and the brush.

The improvement for this particular problem lies in the mounting and installation system for the motor, brush and belt. A resilient mount on both ends of the brush with the installation of roller bearings allows the belt to maintain elasticity, efficiency and the ability to sustain any likely misalignment.

Accordingly, it is necessary to develop a system that will prevent inefficiencies relating to the power transmission through the belt, which often results in fires.

SUMMARY OF INVENTION

According to this invention, as it relates to inclusion of these components, an improved vacuum cleaning operating unit is provided.

A belt gear connects the motor to the brush, which rotates the tension belt. This belt allows the brush to rotate at the same speed of the motor; located at either ends of the brush are roller bearings, which inherently prevent friction thus, avoiding damage and overheating.

Other objectives and advantages will become more apparent in consequent drawings.

BRIEF DESCRIPTION OF DRAWINGS

FIG. 1 illustrates an upright vacuum cleaner 14. in accordance with the present invention. This will be further illustrated in an exploded view in FIG. 2

FIG. 6 is an exploded view of the lower internal portion of the base of the vacuum FIG. 1. as well as a gear type drive belt; roller bearing; drive gear on the brush and resister.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to FIG. 1 and 2, a preferred embodiment vacuum cleaner 14. Referring specifically to FIG. 2, a motor holding bracket 16. is used to hold the motor 18 in place.

A gear driven belt 23 placed on the drive gear 21 of the motor 18 connected to the drive gear on the brush 24, enables the rotation of the tension belt 23. This type of connection allows the brush 20 to rotate at the same speed of the motor 18, all with the aid of a variable resister 25 used as a speed regulator.

These functions combined, provides optimum cleaning capability of the vacuum.

Two roller bearings 26, 27 located on either end of the brush are provided as a prevention of overheating and also damage to the machine.

These preferred embodiments when presented as a unit, works in accordance with the intended functionality of this invention. As a unit the gear driven belt 23. placed on the drive gear 21 will be perfectly aligned to the drive gear on the brush 20. This accommodates smooth rotation of the belt 23. and the ability of the brush 20. to rotate at the same pace as the motor 18. The roller bearings 26, 27. protection from overheating and damage, while a variable resister is provided in the circuitry, so as to regulate the number of revolutions per minute (RPM). This provides optimum cleaning capability on the given surface
